Chapter 4. Power Supply
Power Input
For power input specifications, refer to Table 32 on page 31.
Power Output
The following tables show the power supply capacity per voltage for the IntelliStation M Pro. In the
tables, amperes are designated with an
A
, and milliamperes with an
mA
.
The power supply provides separate voltage sources for the system board and internal storage devices.
The following tables show the maximum power that specific system components can draw. In normal
operation, components draw less current than the maximum shown.
